To respond to haycait 911, for a single plug system everything is there except the plug wires. Note you only need one coil pack for a single plug system, so you have two extra. If you want to go twin plug you need a pickup signal splitter wire or “Y" cable adapter or HPV-1 dual plug applications, part number 72220 ($28) from Clewett. Note that two of the units are missing the covers over the adj dials, Clewett has them as well. I purchased the units over the last several years as part of my RSR build but I am going to install a 95 3.6 with stock ignition so these are avail.

I am not sure of what you are building. If you are using a wong chip I assume you are using the stock dist and won't be using this sytem. Too much tech info to cover here I suggest asking a more detailed question on the tech BB.
